S-1 dilution filings tracker: answers "which companies are registering new share

S-1 dilution filings tracker: answers "which companies are registering new share supply, and where is each registration in its lifecycle?" One row per S-1 registration event: ticker, company name, filing timestamp, market cap at filing, whether the filing is dilutive and/or a resale, shares offered, whether/when it became effective (with days-to-effective), whether/when it was withdrawn, and the SEC accession number + filing URL for the source document.

Use it to flag dilution overhang on small caps, track time-to-effectiveness, or build event studies around registration filings. Filters by ticker and filing-date range (no exact-date parameter on this dataset).

Requires an Alphanume Pro API key. A 403 PRO_SUBSCRIPTION_REQUIRED or DATE_RANGE_RESTRICTED error means the key's plan does not cover the request -- it does not mean the data is missing.
